Introduction:Circulating fluidized bed is of low-temperature combustion,
therefore, nitrogen oxides emissions of such boiler is much lower
than that of coal-powder boiler, and such boiler could directly
desulfurized during combustion process. Circulating fluidized bed
boiler with high desulfurization rate is economical.Circulating fluidized bed boiler could adopt various coal types and
has high combustion efficiency, which is especially suitable for
low quality, low calorific value coal.

HD boilers are efficient, energy saving and environmental friendly,
which can help power plants actualize low pollutant emission based
on their advanced technology and reliable running.

High efficiency: combustion efficiency 96~99%, carbon content in
ash only about 2%, efficiency of boiler reaches 85%.- Suitable for various kinds of coal.- Load can be adjusted in the range of 25%~110%, average 5% in one
minute.- Clean combustion and environment friendly.- Use lime stone mixed into the fuel for desulfuration, rate up to
84%.- NOx emission capacity can be controlled to 150ppm or less.- Ash with low carbon content can be used for cement or
construction materials.

The accessory of power plant high thermal efficiency CFB boiler1. Water wall panels: placed aroud the boiler combustion chamberBoiler water walls are membrane walls that are made of tubes welded
together with or without a strip of metal in between. These walls
form the enclosure of the coal combustion chamber. Water wall tubes
are also referred to as the evaporator section; they contain water
mostly in liquid form which gradually evaporates as it rises in the
boiler.2. superheater and economizerEconomizer, header, air preheater in CFB steam boiler for power
plant.3. Rotary air preheaterRotary Air preheater recovers the heat from the flue gas and
transfers the same to the combustion air to the boiler thus
reducing the fuel consumption of the boiler.The efficiency of Rotary Air preheater is very high compared to the
Tubular air preheater.

Air preheater rotor is divided into compartments in which the
heating elements are packed. Heating elements in the Air preheater
plays a major role for the heat transfer from the flue gas to the
combustion air.

Application:CFB steam boiler is widly used in power station or power plant.
